The DBX 166XL is a versatile dual-channel compressor, limiter and gate, designed to provide precise dynamic control in both studio and live sound environments. Combining DBX's renowned compression technology with independent PeakStop limiting and adjustable gating, it offers a comprehensive solution for controlling dynamics and keeping your signal clean and consistent.

Each channel features a comprehensive set of controls, including compression ratio, threshold, attack and release, allowing you to fine-tune the response to suit different instruments and applications. The OverEasy compression circuit provides smooth, natural-sounding compression, while the PeakStop limiter helps prevent unwanted signal peaks and clipping.

The integrated expander/gate helps reduce unwanted background noise and bleed, making it particularly useful for cleaning up drum microphones, guitar rigs and other audio sources. With its straightforward controls, reliable performance and dual-channel design, the DBX 166XL is an excellent addition to any recording studio, rehearsal space or live sound rack.

Whether you're looking to tighten up bass dynamics, control vocal levels or manage overall signal peaks, the DBX 166XL delivers dependable and flexible dynamic processing.
